[gdal-dev] nodata value assigned via script

[Roger André]

Hi,

I'm getting raster data written by different people who can't seem to use
the same nodata values.  I'm reading the data files via the Python API to
GDAL, and doing various calculations on the data values, then writing new
rasters with the results of my calculations.  Is there a "nodata" value that
I can assign to a pixel that the gdal utilities will recognize as such later
on?  All my other values are 32-bit floating point values, so I'm not sure
what value to assign.

Thanks.

Roger
